Adiponectin and Glucocorticoids Modulate Risk for Preterm Birth: The Healthy Start Study.

PURPOSE: Adiponectin is a potent uterine tocolytic that decreases with gestational age, suggesting it could be a maternal metabolic quiescence factor. Maternal stress can influence preterm birth risk, and adiponectin levels may be stress-responsive. We characterized associations between adiponectin and glucocorticoids with preterm birth and modeled their predictive utility. We hypothesized maternal plasma adiponectin and cortisol are inversely related and lower adiponectin and higher cortisol associate with preterm birth. METHODS: We performed a nested case-control study using biobanked fasting maternal plasma. We included low-risk singleton pregnancies, and matched 1:3 (16 preterm, 46 term). We quantified total, high (HMW), and low molecular weight (LMW) adiponectin using ELISA. We validated an HPLC-MS/MS serum assay for use in plasma, to simultaneously measure cortisol, cortisone, and five related steroid hormones. We used linear/logistic regression to compare group means and machine learning for predictive modeling. RESULTS: The preterm group had lower mean LMW adiponectin (3.07 µg/mL vs. 3.81 µg/mL at 15w0d, P=0.045) and higher mean cortisone (34.4 ng/mL vs. 29.0 ng/mL at 15w0d, P=0.031). The preterm group had lower cortisol-to-cortisone and lower LMW adiponectin-to-cortisol ratios. We found HMW adiponectin, cortisol-to-cortisone ratio, cortisone, maternal height, age, and pre-pregnancy BMI most strongly predicted preterm birth (AUROC=0.8167). In secondary analyses, we assessed biomarker associations with maternal self-reported psychosocial stress. Lower perceived stress associated with a steeper change in cortisone in the term group. CONCLUSION: Overall, metabolic and stress biomarkers associated with preterm birth in this healthy cohort. We identify a possible mechanistic link between maternal stress and metabolism for pregnancy maintenance.

Insulin-like growth factor-1 infusion in preterm piglets does not affect growth parameters of skeletal muscle or tendon tissue.

Prematurity has physical consequences, such as lower birth weight, decreased muscle mass and increased risk of adult-onset metabolic disease. Insulin-like growth factor 1 (IGF-1) has therapeutic potential to improve the growth and quality of muscle and tendon in premature births, and thus attenuate some of these sequalae. We investigated the effect of IGF-1 on extensor carpi radialis muscle and biceps brachii tendon of preterm piglets. The preterm group consisted of 19-day-old preterm (10 days early) piglets, treated with either IGF-1 or vehicle. Term controls consisted of groups of 9-day-old piglets (D9) and 19-day-old piglets (D19). Muscle samples were analysed by immunofluorescence to determine the cross-sectional area (CSA) of muscle fibres, fibre type composition, satellite cell content and central nuclei-containing fibres in the muscle. Tendon samples were analysed for CSA, collagen content and maturation, and vascularization. Gene expression of the tendon was measured by RT-qPCR. Across all endpoints, we found no significant effect of IGF-1 treatment on preterm piglets. Preterm piglets had smaller muscle fibre CSA compared to D9 and D19 control group. Satellite cell content was similar across all groups. For tendon, we found an effect of age on tendon CSA, and mRNA levels of COL1A1, tenomodulin and scleraxis. Immunoreactivity for elastin and CD31, and several markers of tendon maturation, were increased in D9 compared to the preterm piglets. Collagen content was similar across groups. IGF-1 treatment of preterm-born piglets does not influence the growth and maturation of skeletal muscle and tendon.

Community health promotion and medical provision and impact on neonates (CHAMPION2) and support to rural India's public education system and impact on numeracy and literacy scores (STRIPES2): an update to the study protocol (v 11) for a cluster randomised trial in Madhya Pradesh, India.

BACKGROUND: This update outlines amendments to the CHAMPION2/STRIPES2 cluster randomised trial protocol primarily made due to the COVID-19 pandemic and nationwide lockdown in India in 2020. These amendments were in line with national guidelines for health research during the COVID-19 pandemic. METHODS: We did not change the original trial design, eligibility, and outcomes. Amendments were introduced to minimise the risk of COVID-19 transmission and ensure safety and wellbeing of trial staff, participants, and other villagers. CHAMPION2 intervention: participatory learning and action (PLA) and fixed day service (FDS) meeting were revised to incorporate social distancing and hygiene precautions. During the COVID-19 pandemic, PLA participation was limited to pregnant women and birthing partners. STRIPES2 intervention: before/after-school classes were halted for a period and then modified temporarily (reducing class sizes, and/or changing meeting places) with hygiene and safe distancing practices introduced. DATA COLLECTION: The research team gathered as much information as possible from participants by telephone. If the participant had no telephone or could not be contacted by telephone, data were collected in person. COVID-19 precautions: trial teams were trained on COVID-19 precautions and used personal protective equipment whilst in the villages for trial-related activities. After restarting the trial between June and September 2020 in a phased manner, some trial activities were suspended again in all the trial villages from April to June 2021 due to the second wave of COVID-19 cases and lockdown imposed in Satna, Madhya Pradesh. Trial timelines were also revised, with outcomes measured later than originally planned. TRIAL REGISTRATION: Clinical Trial Registry of India CTRI/2019/05/019296. Registered 23 May 2019. https://ctri.nic.in/Clinicaltrials/pmaindet2.php?EncHid=MzExOTg=&Enc=&userName=champion2 .

Prioritise safety, optimise success! Return to rugby postpartum.

Pregnancy and childbirth involve substantial physical, physiological and psychological changes. As such, postpartum rugby players should be supported and appropriately prepared to return to the demands of rugby alongside the additional demands of motherhood. This review aims to discuss specific perinatal considerations that inform a rugby player's readiness to return-to-sport postpartum and present an approach to rehabilitation. Before engaging in full rugby training and matchplay, postpartum players should have progressed through the initial phases of rehabilitation and graded sports-specific training to prepare them for the loads they will be exposed to. Additional rehabilitation considerations include minimising deconditioning during pregnancy; medical concerns; the abdominal wall; the pelvic floor; perinatal breast changes, breastfeeding and risk of contact breast injury; body mass; nutritional requirements; hormonal considerations; athlete identity and psychological considerations; joining team training; return to contact and tackle training; evaluating player load tolerance and future research, policy and surveillance needs. A whole-systems, biopsychosocial approach following an evidence informed return-to-sport framework is recommended when rehabilitating postpartum rugby players. Health and exercise professionals are encouraged to use the perinatal-specific recommendations in this review to guide the development of postpartum rehabilitation protocols and resources.

'Drowned in a Sea of Inhumanity': Natural Childbirth, Postnatal Depression and the National Childbirth Trust, 1956-80s.

During the 1970s, the National Childbirth Trust (NCT) began to provide information and support to women experiencing postnatal mental illness, building on its promotion of natural childbirth and emphasis on the emotional wellbeing of women around birth, which had occupied the organisation since its establishment in 1956. This article argues that, alongside emotional, social and medical factors, the NCT attributed postnatal depression to the shift to hospital deliveries, involving high levels of intervention and frustrating women's choice and agency. While sharing ambitions to improve care in childbirth and giving women a voice in describing their experiences, it is suggested that the NCT's relationship with the feminist health movement remained ambiguous. The article also explores the NCT's collaboration with a variety of experts and advisors, some of whom emphasised the risk of postnatal depression to the bonding process and infant's development, potentially exacerbating the mental distress of new mothers.

Trauma-informed support after a complicated childbirth - An early intervention to reduce symptoms of post-traumatic stress, fear of childbirth and mental illness.

OBJECTIVE: Women who experience obstetric interventions and complications during childbirth have an increased risk of developing postnatal post-traumatic stress and mental illness. This study aimed to test the effect of a trauma-informed support programme based on psychological first aid (PFA) to reduce the mothers' symptoms of stress, fear of childbirth (FOC), anxiety and depression after a complicated childbirth. METHODS: The study population consisted of women ≥ 18 years old who had undergone a complicated childbirth (i.e. acute or emergency caesarean section, vacuum extraction, child in need of neonatal care, manual placenta removal, obstetric anal sphincter injury, shoulder dystocia or major haemorrhage (>1000 ml)). A total of 101 women participated in the study, of whom 43 received the intervention. Demographic questions and three self-assessment instruments measuring stress symptoms, FOC, anxiety and depression were answered one to three months after birth. RESULTS: The women in the intervention group scored significantly lower on the stress symptom scale, with a halved median score compared to the control group. There was no significant difference between the groups regarding FOC, depression and anxiety. CONCLUSION: Our results indicate that this PFA-based support programme might reduce post-traumatic stress symptoms in women who have gone through a complicated childbirth. With further studies in a larger population, this support programme has the potential to contribute to improved maternal care optimizing postnatal mental health.

Acceptability of data linkage to identify women at risk of postnatal complication for the development of digital risk prediction tools and interventions to better optimise postnatal care, a qualitative descriptive study design.

BACKGROUND: Pregnancy acts as a cardiovascular stress test. Although many complications resolve following birth, women with hypertensive disorder of pregnancy have an increased risk of developing cardiovascular disease (CVD) long-term. Monitoring postnatal health can reduce this risk but requires better methods to identity high-risk women for timely interventions. METHODS: Employing a qualitative descriptive study design, focus groups and/or interviews were conducted, separately engaging public contributors and clinical professionals. Diverse participants were recruited through social media convenience sampling. Semi-structured, facilitator-led discussions explored perspectives of current postnatal assessment and attitudes towards linking patient electronic healthcare data to develop digital tools for identifying postpartum women at risk of CVD. Participant perspectives were gathered using post-it notes or a facilitator scribe and analysed thematically. RESULTS: From 27 public and seven clinical contributors, five themes regarding postnatal check expectations versus reality were developed, including 'limited resources', 'low maternal health priority', 'lack of knowledge', 'ineffective systems' and 'new mum syndrome'. Despite some concerns, all supported data linkage to identify women postnatally, targeting intervention to those at greater risk of CVD. Participants outlined potential benefits of digitalisation and risk prediction, highlighting design and communication needs for diverse communities. CONCLUSIONS: Current health system constraints in England contribute to suboptimal postnatal care. Integrating data linkage and improving education on data and digital tools for maternal healthcare shows promise for enhanced monitoring and improved future health. Recognised for streamlining processes and risk prediction, digital tools may enable more person-centred care plans, addressing the gaps in current postnatal care practice.

Male-Biased Vulnerability of Mouse Brain Tryptophan/Kynurenine and Glutamate Systems to Adolescent Exposures to Concentrated Ambient Ultrafine Particle Air Pollution.

Air pollution (AP) exposures have been associated with numerous neurodevelopmental and psychiatric disorders, including autism spectrum disorder, attention deficit hyperactivity disorder and schizophrenia, all male-biased disorders with onsets from early life to late adolescence/early adulthood. While prior experimental studies have focused on effects of AP exposures during early brain development, brain development actually extends well into early adulthood. The current study in mice sought to extend the understanding of developmental brain vulnerability during adolescence, a later but significant period of brain development and maturation to the ultrafine particulate (UFPs) component of AP, considered its most reactive component. Additionally, it examined adolescent response to UFPs when preceded by earlier developmental exposures, to ascertain the trajectory of effects and potential enhancement or mitigation of adverse consequences. Outcomes focused on shared features associated with multiple neurodevelopmental disorders. For this purpose, C57Bl/6J mice of both sexes were exposed to ambient concentrated UFPs or filtered air from PND (postnatal day) 4-7 and PND10-13, and again at PND39-42 and 45-49, resulting in 3 exposure postnatal/adolescent treatment groups per sex: Air/Air, Air/UFP, and UFP/UFP. Features common to neurodevelopmental disorders were examined at PND50. Mass exposure concentration from postnatal exposure averaged 44.34 µg/m3 and the adolescent exposure averaged 49.18 µg/m3. Male brain showed particular vulnerability to UFP exposures in adolescence, with alterations in frontal cortical and striatal glutamatergic and tryptophan/serotonergic neurotransmitters and concurrent reductions in levels of astrocytes in corpus callosum and in serum cytokine levels, with combined exposures resulting in significant reductions in corpus callosum myelination and serum corticosterone. Reductions in serum corticosterone in males correlated with reductions in neurotransmitter levels, and reductions in striatal glutamatergic function specifically correlated with reductions in corpus callosum astrocytes. UFP-induced changes in neurotransmitter levels in males were mitigated by prior postnatal exposure, suggesting potential adaptation, whereas reductions in corticosterone and in corpus callosum neuropathological effects were further strengthened by combined postnatal and adolescent exposures. UFP-induced changes in females occurred primarily in striatal dopamine systems and as reductions in serum cytokines only in response to combined postnatal and adolescent exposures. Findings in males underscore the importance of more integrated physiological assessments of mechanisms of neurotoxicity. Further, these findings provide biological plausibility for an accumulating epidemiologic literature linking air pollution to neurodevelopmental and psychiatric disorders. As such, they support a need for consideration of the regulation of the UFP component of air pollution.

Investigating factors influencing decision-making around use of breastmilk substitutes by health care professionals: a qualitative study.

BACKGROUND: Breastfeeding is recognized as the gold standard of infant feeding and nutrition. The World Health Organization recommends exclusive breastfeeding (EBF) of infants for the first 6 months of life. A variety of factors may impact breastfeeding practices in-hospital which may continue after hospital discharge, such as the use of breastmilk substitutes (BMS). The Baby-Friendly Initiative (BFI), which aims to promote and support breastfeeding practices, established a target rate of 75% for EBF from birth to hospital discharge. Currently, this target is not being met at The Ottawa Hospital (TOH), indicating there is room for improvement in EBF rates. The purpose of this study is to explore health care professionals (HCP) decision-making around use of BMS and identify factors that drive the use of BMS with and without medical indications. METHODS: In this qualitative study, semi-structured interviews were conducted with HCPs within TOH from January to June 2022. All participants had experience in maternity or postpartum care and were probed on factors influencing use of BMS at this institution. Interview transcripts were coded using an inductive approach. RESULTS: A total of 18 HCPs were interviewed including physicians, midwives, lactation consultants, and registered nurses. Multilevel barriers influencing the use of BMS were categorized into patient, HCP, and institution-level factors. Subthemes that emerged ranged from parental preferences, training differences amongst HCPs, to budget and staffing issues. Over half of HCPs were prepared to answer questions on EBF and were familiar with the BFI. Although most were supportive of this institution receiving BFI designation, a few providers raised concerns of its impact on parents who would like to supplement. CONCLUSIONS: Several modifiable factors influencing decision-making for use of BMS were identified. These findings will be used to inform unit leads, help identify effective strategies to address modifiable barriers, and develop tailored breastfeeding supports to improve EBF rates.

Prevalence and Risk Factors of Prenatal and Postnatal Depressive Symptoms in Babol Pregnancy Mental Health Registry: A Cross-Sectional Study.

BACKGROUND: Prenatal and postnatal depression (PND) is associated with adverse outcomes for mother, fetus, and child. The aim of study was to examine the prevalence and risk factors of prenatal and postnatal depressive symptoms. MATERIALS AND METHODS: This was a cross-sectional and hospital-based survey of 2305 pregnant women and post-partum women (18-48 years) that was registered in the Babol Pregnancy Mental Health Registry (BPMHR) database from June 2020 to March 2021. Two questionnaires, including demographics and depression, were analyzed in this study. Also, the Edinburg Postnatal Depression Scale (EPDS) was used to assess the depressive symptoms. Independent t test and the analysis of variance were used to compare the means. Multiple logistic regressions were used to determine risk factors for depressive symptoms. RESULTS: According to the EPDS scale, the prevalence of depressive symptoms was 19.8% in the pregnant woman group in comparison with the postpartum period (11.6%). Risk factors for antenatal depressive symptoms were parity (women with parity ≥ 4 vs. 1 parity, ß=1.808, P=0.020), two groups of gestational age (gestational age ≤12 weeks vs. 28 weeks, ß=1.562 P=0.030) as well as (gestational age 21-27 weeks vs. 28 weeks (ß=1.586, P=0.033), and high-risk pregnancy (high-risk vs. low-risk pregnancy, ß=1.457, P=0.003). For postnatal depressive symptoms, none of the factors were a significant risk. CONCLUSION: Prenatal and postnatal depressive symptoms should be screened, particularly for women in the first and second trimesters, with high parity, and those with a high-risk pregnancy, as recommended by the present study.

Changes in maternity care policies and practices that support breastfeeding as measured by the Ten Steps to Successful Breastfeeding - United States, 2018-2022.

BACKGROUND: Experiences during the birth hospitalization affect a family's ability to establish and maintain breastfeeding. The Ten Steps to Successful Breastfeeding (Ten Steps) describe evidence-based hospital policies and practices shown to improve breastfeeding outcomes. We aim to describe hospitals' implementation of the Ten Steps, changes over time, and hospitals' implementation of a majority (≥ 6) of the Ten Steps by hospital characteristics and state. METHODS: The biennial Maternity Practices in Infant Nutrition and Care (mPINC) survey assesses all hospitals in the United States (including the District of Columbia and territories) that routinely provide maternity care services. We analyzed data from 2018, 2020, and 2022 survey cycles to describe trends in the prevalence of hospitals implementing maternity care policies and practices that are consistent with the Ten Steps. Differences were calculated using the absolute difference in percentage-points between 2018 and 2022. RESULTS: Between 2018 and 2022, the percentage of hospitals that implemented Step 2: Staff Competency and Step 5: Support Mothers with Breastfeeding increased 12 and 8 percentage points, respectively. The percentage of hospitals that implemented Step 6: Exclusive Breastfeeding Among Breastfed Infants was 7 percentage points lower in 2022 than 2018. Implementation of the remaining seven steps did not change by more than 5 percentage points in either direction between 2018 and 2022. Nationally, the percentage of hospitals that implemented ≥ 6 of the Ten Steps increased from 44.0% in 2018 to 51.1% in 2022. Differences were seen when comparing implementation of ≥ 6 of the Ten Steps by hospital characteristics including state, hospital size, and highest level of neonatal care offered. CONCLUSIONS: Nationally, maternity care policies and practices supportive of breastfeeding continued to improve; however, certain practices lost progress. Differences in implementation of the Ten Steps were observed across states and by certain hospital characteristics, suggesting more work is needed to ensure all people receive optimal breastfeeding support during their delivery hospitalization.

Women's experiences and views of routine assessment for anxiety in pregnancy and after birth: A qualitative study.

BACKGROUND: Anxiety in pregnancy and postnatally is highly prevalent but under-recognized. To identify perinatal anxiety, assessment tools must be acceptable to women who are pregnant or postnatal. METHODS: A qualitative study of women's experiences of anxiety and mental health assessment during pregnancy and after birth and views on the acceptability of perinatal anxiety assessment. Semi-structured interviews were conducted with 41 pregnant or postnatal women. Results were analysed using Sekhon et al.'s acceptability framework, as well as inductive coding of new or emergent themes. RESULTS: Women's perceptions of routine assessment for perinatal anxiety were generally favourable. Most participants thought assessment was needed and that the benefits outweighed potential negative impacts, such as unnecessary referrals to specialist services. Six themes were identified of: (1) Raising awareness; (2) Improving support; (3) Surveillance and stigma; (4) Gatekeeping; (5) Personalized care and (6) Trust. Assessment was seen as a tool for raising awareness about mental health during the perinatal period and a mechanism for normalizing discussions about mental health more generally. However, views on questionnaire assessments themselves were mixed, with some participants feeling they could become an administrative 'tick box' exercise that depersonalizes care and does not provide a space to discuss mental health problems. CONCLUSION: Routine assessment of perinatal anxiety was generally viewed as positive and acceptable; however, this was qualified by the extent to which it was informed and personalized as a process. Approaches to assessment should ideally be flexible, tailored across the perinatal period and embedded in continuity of care.

Mature enteric neurons have the capacity to reinnervate the intestine with glial cells as their guide.

Here, we establish that plasticity exists within the postnatal enteric nervous system by demonstrating the reinnervation potential of post-mitotic enteric neurons (ENs). Employing BAF53b-Cre mice for selective neuronal tracing, the reinnervation capabilities of mature postnatal ENs are shown across multiple model systems. Isolated ENs regenerate neurites in vitro, with neurite complexity and direction influenced by contact with enteric glial cells (EGCs). Nerve fibers from transplanted ENs exclusively interface and travel along EGCs within the muscularis propria. Resident EGCs persist after Cre-dependent ablation of ENs and govern the architecture of the myenteric plexus for reinnervating ENs, as shown by nerve fiber projection tracing. Transplantation and optogenetic experiments in vivo highlight the rapid reinnervation potential of post-mitotic neurons, leading to restored gut muscle contractile activity within 2 weeks. These studies illustrate the structural and functional reinnervation capacity of post-mitotic ENs and the critical role of EGCs in guiding and patterning their trajectories.

Melanocortin-receptor 4 activation modulates proliferation and differentiation of rat postnatal hippocampal neural precursor cells.

Postnatal hippocampal neurogenesis is essential for learning and memory. Hippocampal neural precursor cells (NPCs) can be induced to proliferate and differentiate into either glial cells or dentate granule cells. Notably, hippocampal neurogenesis decreases dramatically with age, partly due to a reduction in the NPC pool and a decrease in their proliferative activity. Alpha-melanocyte-stimulating hormone (α-MSH) improves learning, memory, neuronal survival and plasticity. Here, we used postnatally-isolated hippocampal NPCs from Wistar rat pups (male and female combined) to determine the role of the melanocortin analog [Nle4, D-Phe7]-α-MSH (NDP-MSH) in proliferation and fate acquisition of NPCs. Incubation of growth-factor deprived NPCs with 10 nM NDP-MSH for 6 days increased the proportion of Ki-67- and 5-bromo-2'-deoxyuridine (BrdU)-positive cells, compared to the control group, and these effects were blocked by the MC4R antagonist JKC-363. NDP-MSH also increased the proportion of glial fibrillar acidic protein (GFAP)/Ki-67, GFAP/sex-determining region Y-box2 (SOX2) and neuroepithelial stem cell protein (NESTIN)/Ki-67-double positive cells (type-1 and type-2 precursors). Finally, NDP-MSH induced peroxisome proliferator-activated receptor (PPAR)-γ protein expression, and co-incubation with the PPAR-γ inhibitor GW9662 prevented the effect of NDP-MSH on NPC proliferation and differentiation. Our results indicate that in vitro activation of MC4R in growth-factor-deprived postnatal hippocampal NPCs induces proliferation and promotes the relative expansion of the type-1 and type-2 NPC pool through a PPAR-γ-dependent mechanism. These results shed new light on the mechanisms underlying the beneficial effects of melanocortins in hippocampal plasticity and provide evidence linking the MC4R and PPAR-γ pathways in modulation of hippocampal NPC proliferation and differentiation.

Postnatal social support experiences in primiparous women in Korea: a phenomenological study.

PURPOSE: Social support is essential for postpartum well-being, but little is known about the postpnatal social support preferred by primiparous women. This study aimed to comprehensively understand and describe the meaning of postnatal social support experience in primiparous women. METHODS: The participants were seven primiparous women who were within 1 year after childbirth, recruited through purposive and snowball sampling from an online parenting community. The data were collected through in-depth interviews from November 14 to 28, 2022. Participants were interviewed face-to-face or via phone or online platform, according to their choice. Colaizzi's phenomenological qualitative research method was applied to analyze the meaning of the participants' experience. RESULTS: Five theme clusters and fourteen themes were identified from the data. The five theme clusters are as follows: (1) Shortcomings of the childbirth and postpartum care system I learned through my experience; (2) Government policies focusing on childbirth and child-rearing rather than postpartum recovery; (3) Driving force of postpartum recovery: Shared childbirth process; (4) Childcare on my own; and (5) Conflicted between being a stay-at-home mom and a working mom under inadequate maternity protection policies. CONCLUSION: Despite postpartum support from the government that was perceived as inadequate, first-time mothers regained confidence and motivation for parenting with the help of family, peers, and social networks. First-time mothers need support from professionals and reliable online communities for postpartum recovery and parenting.

The first 100 days after childbirth: cross-sectional study of maternal clinical events and health needs from primary care.

BACKGROUND: The first 100 days after childbirth are important for women recovering from pregnancy and birth. AIM: To describe the most common clinical events or health needs documented in women's primary care records in the first 100 days after childbirth. DESIGN AND SETTING: Cross-sectional study using electronic health records from United Kingdom primary care data. METHOD: We examined the primary care records from childbirth up to 100 days after childbirth of women aged 16-49 years who had given birth to a single live infant 2006-2016 in IMRD. We identified the most common clinical events or health needs based on documented symptoms, diagnoses and medications. We explored how these varied by patient characteristic. RESULTS: We identified 925,712 contacts during the 100 days following 309,573 births. We found that women were most likely to use primary care to have a postnatal visit or check (60.6%), for monitoring (such as a blood pressure reading) (49.9%), and to access contraception (49.7%). Younger women were more likely to have contacts for preventative care compared to older women but were less likely to have contacts for ongoing mental and physical symptoms or conditions, and pre-existing conditions. The highest peak in contacts occurred 42 days after birth, and related to a postnatal check or visit, monitoring a patient and recording lifestyle factors (such as smoking status). CONCLUSION: Primary care services should seek to match the needs of new mothers taking account of a high volume of contacts for a broad range of planned and responsive care following childbirth.

Women utilisation, needs and satisfaction with postnatal follow-up care in Oman: A cross-sectional survey.

BACKGROUND: In Oman, there is a lack of data on utilisation, needs and women's satisfaction with care and information provided during postnatal follow-up period. AIM: To investigate postnatal follow-up care utilisation and women's needs; level of postnatal information received and satisfaction with services. METHODS: A purposive sample of women (n = 500), recruited in the immediate postnatal period at one metropolitan and one regional birthing hospital in Oman. An electronic survey link was sent to participants at 6-8 weeks postnatally. Quantitative variables were analysed as frequencies and chi-squared test. RESULTS: A total of 328 completed surveys were received; a response rate of 66 %. Most respondents were located in the metropolitan area (n = 250) and between 20 and 39 years (n = 308). Utilisation was low as women reported no need or no benefit in attending. Women's information needs were not sufficiently met by HCPs, requiring women to seek information from family and the internet to meet their needs. Satisfaction with services was mostly neither satisfied nor dissatisfied (30 %) or satisfied (30 %). CONCLUSION: Postnatal follow-up care utilisation in both metropolitan and regional areas is less than optimal and not utilised as there was no advice to attend or no appointment date/time given, no benefit experienced previously, no need and information needed sourced from family or the internet. The information provided by postnatal follow-up care consumers can be used to enhance service delivery, inform future updates to the national maternity care guidelines, and provides a baseline for future evaluation and research.

Access to maternal health services for Indigenous women in low- and middle-income countries: an updated integrative review of the literature from 2018 to 2023.

INTRODUCTION: Ninety-seven per cent of Indigenous Peoples live in low-and middle-income countries (LMICs). A previous systematic integrative review of articles published between 2000 and 2017 identified numerous barriers for Indigenous women in LMICs in accessing maternal healthcare services. It is timely given the aim of achieving Universal Health Coverage in six years' time, by 2030, to undertake another review. This article updates the previous review exploring the recent available literature on Indigenous women's access to maternal health services in LMICs identifying barriers to services. METHODS: An integrative review of literature published between 2018 and 2023 was undertaken. This review followed a systematic process using Whittemore and Knafl's five-step framework for integrative reviews and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 944 articles were identified from six databases: Academic Search Premier, MEDLINE, Psychology and Behavioral Sciences Collection, APA PsycInfo, CINAHL Plus with Full Text and APA PsycArticles (through EBSCOhost). The search was undertaken on 16 January 2023. After screening of the title/abstract and the full text using inclusion and exclusion criteria 26 articles were identified. Critical appraisal resulted in 24 articles being included in the review. Data were extracted using a matrix informed by Penchansky and Thomas's taxonomy, extended by Saurman, which focused on six dimensions of access to health care: affordability, accessibility, availability, accommodation, acceptability and awareness. Ten studies took place in Asia, 10 studies were from the Americas and four studies took place in the African region. Seventeen articles were qualitative, two were quantitative and five were mixed methods. The methods for the integrative review were prespecified in a protocol, registered at Open Science Framework. RESULTS: Barriers identified included affordability; community awareness of services including poor communication between providers and women; the availability of services, with staff often missing from the facilities; poor quality services, which did not consider the cultural and spiritual needs of Indigenous Peoples; an overreliance on the biomedical model; a lack of facilities to enable appropriate maternal care; services that did not accommodate the everyday needs of women, including work and family responsibilities; lack of understanding of Indigenous cultures from health professionals; and evidence of obstetric violence and mistreatment of Indigenous women. CONCLUSION: Barriers to Indigenous women's access to maternal health services are underpinned by the social exclusion and marginalisation of Indigenous Peoples. Empowerment of Indigenous women and communities in LMICs is required as well as initiatives to challenge the stigmatisation and marginalisation that they face. The importance of community involvement in design and interventions that support the political and human rights of Indigenous Peoples are required. Limitations of this review include the possibility of missing articles as it was sometimes unclear from the articles whether a particular group was from an Indigenous community. More research on access to services in the postnatal period is still needed, as well as quality quantitative research. There is also a lack of research on Indigenous groups in North Africa, and in sub-Saharan Africa - especially hunter-gatherer groups - as well as the impact of COVID-19 on access to services.

Activity-dependent dendrite patterning in the postnatal barrel cortex.

For neural circuit construction in the brain, coarse neuronal connections are assembled prenatally following genetic programs, being reorganized postnatally by activity-dependent mechanisms to implement area-specific computational functions. Activity-dependent dendrite patterning is a critical component of neural circuit reorganization, whereby individual neurons rearrange and optimize their presynaptic partners. In the rodent primary somatosensory cortex (barrel cortex), driven by thalamocortical inputs, layer 4 (L4) excitatory neurons extensively remodel their basal dendrites at neonatal stages to ensure specific responses of barrels to the corresponding individual whiskers. This feature of barrel cortex L4 neurons makes them an excellent model, significantly contributing to unveiling the activity-dependent nature of dendrite patterning and circuit reorganization. In this review, we summarize recent advances in our understanding of the activity-dependent mechanisms underlying dendrite patterning. Our focus lays on the mechanisms revealed by in vivo time-lapse imaging, and the role of activity-dependent Golgi apparatus polarity regulation in dendrite patterning. We also discuss the type of neuronal activity that could contribute to dendrite patterning and hence connectivity.
